Since BTCs decline from its all time high in December you can see it hasn't gone outside of this downward channel (in green) and today so far seems to be no exception. Another extremely reliable line of support BTC has not dipped under and has in fact bounced off of several times in the last 6 years or so is the 200 day exponential moving average (blue line) on the day chart. I predict that once again it will stay above both the bottom line of the green channel and also above the 200EMA. Set your stop losses an position exits accordingly...if it falls under that line I will be exiting my position but may increase my position slightly above those lines with the anticipation that it will bounce upwards.
